Mono Ethylene Glycol is one of the most important fluids in the modern Oil + Gas industry. Indeed, in many areas of the offshore, the monitoring of MEG has become a necessity. CONTROS’ HydroC™ / MEG is a unique underwater leakage sensor solving the global problems of the in-situ measurements of Mono Ethylene Glycol. Applications include offshore pipeline inspections, leakage detection, water & waste water treatment tasks and risk management solutions. HydroC™ / MEG - Sensor for Mono Ethylene Glycol (Anti-freeze) in water

Function principle MEG diffuses out of the liquid through a special silicone membrane (patented) into the detector chamber. Inside the chamber MEG gas is measured electronically with an adaptive analysing system and converts into the output signals. Patent pending.

Membrane Standard: 10 µm silicone membrane. Other options or anti fouling device on request Operational depth 2000 m, 4000m, 6000m

Temperature -5°C… +50 °C, other ranges on request Measuring range 0…100% MEG, other ranges on request Resolution 0.1 %
